High HC Readings 900 1994

Just had my annual state emissions testing completed and noticed the hydrocarbons (HC) readings were a bit high.
At 15 mph, the test results showed a reading of 40ppm (59ppm Max & 25ppm Average). At 25 mph, the test results was 22ppm (34ppm Max & 14ppm Average).
The B230FT passed the test, but the technician commented those HC readings were a bit high.
I've also noticed my gas mileage has dropped off down to 14-15mpg range.
Oxygen Sensor time?
Opinions please.
